COMBINED PUMP AND FORCE-FEED OIL CAN.

Application filed February 14, 1924. Serial No. 692,636.

To all whom it may concem:

Be it known that I, GUSTAVE LIDSEEN, a citizen of the United States, anda resident of the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in CombinedPump and Force-Feed Oil Can: and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the numerals of referencemarkedthereon, which form a part of this specification. V

This invention relates to a combination forced feed and pumping oil can;

It is an object of this invention to provide an oil can which can beconverted from a forced feed one to a pumping one, whereby it ispossible to lubricate bearings above the can by using the pumpingfeature, and.

whereby it is possible to lubricate other bearings especially thoserequiring a downward tilting of the oil can by the forced feed thereof.

The invention comprises the novel structure and combinations hereinafterdescribed and more particularly pointed out anddelined in the appendedclaims.

In the accompanying drawings which illustrate a preferred form of thisinvention and in which similar reference numerals refer to similarfeatures in the different views: Figure 1 is an elevational view of theoil can. I

Fig. 2 is an enlarged top plan view of the oil can with the nozzle shownin section.

Fig. 3 is an enlarged vertical section through the oil can showing partsin elevation.

Fig. 4 is an enlarged bottom plan view of the cover or closure for theoil can showing the feed pipe in section.

Fig. 5 is an enlarged sectional view through the lower end of the feedpipe.

Fig. 6 is an enlarged sectional view through the forced feed and pumpingmechanism of the oil can.

Fig. 7 is an enlarged sectional view through the forced feed and pumpingmechanism showing parts in different positions.

Fig. 8 is a sectional view of a slightly modified form of oil can withparts in elevation.

Referring to Figs. 1 to 7 of the drawings which illustrate embodiment ofthis invent n, t ere i shownan o l can embed)- tially flanged forattachment to the body portion which is likewise partially flanged uponits upper end. A sleeve 5 is secured within the cylindrical portion ofthe 1102'. zle and depends thcrebelow and near the up per end of thisdepending portion are slots 6 for the admission of oil into the sleevewhen the can is properly tilted. These slots constitute inlet ports whenit is desired to merely force the oil from the can instead of pumping aswill later appear.

A partition 7 or the like is secured in the upper end of the sleeve 5.In the present instance, the partition is formed of a pair of spaceddisks which are centrally apertured for the reception of the upper endof an oil feed pipe 8 which extends into the lu bricant container at anangle to a point adjacent the bottom; the lower end being closed by aball valve 9 confined by a cap 10. A concave valve 11 is seated in theup per end of the pipe 8 and normally closes the same. A stud 12 dependsfrom this concave valve, and a leaf spring 13 attached at one end to thelower end of the stud, and secured at its other end to the partitionyieldingly maintains the valve 11 in closed position. A pair of inletports 11 are formed in the upper end of the feed pipe through which thatlubricating oil is adapt-- ed to pass that enters the ports 6 as willlater appear. 1

A piston 15 is mounted for reciprocation in the sleeve 5. In the presentinstance, this piston consists of a hollow cylindrical mem ber closed atits lower end except where the same is centrally apertured for thereception of the feed pipe 8. A coil spring 16 is confined in the sleeve5 between the partition 7 and the piston for normally depress-- ing thepiston.

The cover or closure2 is provided with a concave recess or seat 17plainly shown in Fig. 6. A lever 18 preferably constructed of severalparts is fulcrumed in this recess. This lever comprises a concavefulcrum 19 seated for sliding movement in the concave recess 17, anupper power arm 18 secured to said fulcrum and a lower weight arm 18which extends through a suitable slot in the closure. A suitably curvedshield 20 is posii ne eve the lower end of h sl t. and

'curveddownwardly as indicated at 21 the lever arm 18 extends throughthis pumping feature being adapted for oiling shield which has a slidingmovement on the bottom of the closure.

The weight arm 18 of the lever 18 comprises a forked end 21 which isshown in the present instance as a separable member attached thereto.This forked end has a downward bend as is indicated at 21 where by anupward slope is imparted to the outer portions of said fork. are adaptedto engage the bottom of the piston 15 and as it is necessary for thesame to slide over said bottom, they are preferably In order to addrigidity to the forked end, a bracing strip 22 is attached upon the arm18 for engaging the outer end of the member 21.

As the lever 18 is oscillated, it will raise and lower the piston 15 forpumping oil through the nozzle 3, provided the ports 6 are closed. Inorder to close these ports during the pumping operation, the piston 15is elevated by means of the lever 18, into the position shown'in Fig. 6in which the ports 6 are closed, and thelink 23 which is pivoted to thearm 18 of the lever is swung to engage the nozzle. With the link 23 inthe position shown in Fig. 6, the limits of reciprocation of the piston15 will be such as to always close the slots or ports 6. It is thereforepossible to pump oil from the can through the feed pipe 8 when the ports6 are closed.

hen it is desired to oil a bearing by tilting the can or inverting thesame, the link 23 is swung outof engagement with the nozzle whereby thepiston will, be forced down by the spring 16 to its lower limit as shownin Fig.7, whereby the ports 6 are opened for the entrance of oil abovethe piston, assuming of course that the can has been sufliciently tiltedfor such a purpose. From the chamber above the piston, the oil will flowthrough the ports 14 into the feed pipe 8, and may be forced therefrominto the nozzle 3 by operating the lever 18, producing what may betermed a forced feed.

In Fig. 8, there is shown a slightly differentform ofoil can, 1 having acover 2 provided with a nozzle 3 which has a lower cylindrical portionas the first form, with a similar partition 7 and feed pipe 8 and piston15 operable by a lever 18- as in the first form. The sleeve 5 shown inthe first form is, however, omitted in this second form so that thepiston reciprocates directly against the wall of the nozzle. This secondformis hence only adapted for pumping oil and is not adapted for forcedfeeding as the first form.

From the foregoing, it will be apparent that I have devised a novel formof oil or lubricating can which is very convenient for use in oilingbearings in any position; the

The ends of the fork bearings that do not require undue tilting of thecan, while the forced feed feature being adapted for oiling bearingswhich require considerable tilting of the can.

I am aware that numerous details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted otherwisethannecessitated by the prior art.
